What is the difference between data structure and abstract data type?

An Abstract Data Type is an interface that interacts with a data structure. A Data Structure is an implementation of the ADT. for example. If you were going to create a linked list you would create an Interface listing all the methods required by the list. Then in the linked list class you would code how the list uses these methods. Hope this helps :)

What is the difference between relation and table in data base?

Table is where the data is stored and in a well designed schema a table represents some real world object such as CUSTOMER, ORDER, etc., Now the real world objects have relationships. For example, a CUSTOMER has many ORDERS. To represent this relationship a database relationship was invented.


Difference between activity diagram and dfd?

In data flow diagrams, the lines between "boxes" represent data that flows between components of a system. Because these only show the flow of data, they do not give an indication of sequencing.In activity diagrams, those lines are simply transitions between activities and do not represent data flow at all. They more represent the sequencing of activities and decisions. You can tell from these what order things happen in.


What undesirable dependencies are avoided when a relation is in 3NF?

3rd normal form helps reduce redundant data, avoid data anomalies and ensure referential integrity.

Which of the abstract data type can be used to represent to many to many relation?

A graph is an abstract data type that can effectively represent many-to-many relationships. In a graph, nodes (or vertices) represent entities, while edges represent the connections or relationships between them, allowing for multiple connections between different nodes. This structure is ideal for modeling complex relationships, such as social networks or collaborative systems, where numerous entities interact with one another in various ways.

What are the key differences between floating point and integer data types?

The key difference between floating point and integer data types is how they store and represent numbers. Integer data types store whole numbers without any decimal points, while floating point data types store numbers with decimal points. Integer data types have a fixed range of values they can represent, while floating point data types can represent a wider range of values with varying levels of precision. Floating point data types are typically used for calculations that require decimal precision, while integer data types are used for whole number calculations.


Abstract data type that store a whole numbers?

All data types can be used to store a whole number, even the data types that can store a decimal number.


What are characters that represent objects?

In programming, characters like letters, digits, and special symbols represent different objects or data types. For example, the character 'a' can represent a letter, '1' can represent a digit, and '%' can represent a special symbol. These characters are often used to store and manipulate data in a computer program.


What are abstract data types?

Abstract Data Types An Abstract Data Type (ADT) is a data type that has been created by a programmer – i.e., it is not built-in in the programming language. As any other data types, an ADT is composed of a domain (the set of values belonging to the data type) and a collection of operations to manipulate such values. The only difference is that such data type will be constructed by the programmer. When we build an ADT we really want to apply the principles of encapsulation and information hiding mentioned earlier. This means that, once we have finished building the data type, we wish others to use the data type exclusively through the operations we provide, and in no other way. In particular, to protect our implementation and guarantee the ability to evolve software, we want to ensure that the implementation of the ADT is hidden from other users.


What is the use of constructors?

Constructors are used in object-oriented programming languages to create usable instances of abstract data types (classes).
